The kinds of organisations paying literal tons of euros/dollars/whatever to their CEO's? I have yet to find a charitable organisation that doesn't basically funnel my money into the pocket of someone like that.
If you object to high CEO compensation for large NGOs, support small NGOs. They are typically run on a shoe-string, and the leaders are idealists who are definitely not in it for the money. One of my favorites is the Alliance for Tompotika (http://tompotika.org), run by a true visionary and very effective.
